Playback problems

I have installed netjuke successfully on two different boxes. The first one was on my own box and the second one is on a roomates computer. My roomates computer is running windows xp pro and is running apache and mysql using the latest version of netjuke. Everything seems to be working fine, his music is all listed and the database queries fine and everything. But, for some reason the only player that will stream his music is windows media player. I have tried a couple of different players such as winamp 2 and winamp 3, i also think that he tried musicmatch jukebox all with no success. I have tried these different players on different machines as well, again no success. The odd thing about the whole deal is that his configuration is identical to mine and my computer has no trouble streaming to different types of players. The only thing that i can think of that makes our configurations different is that my roomates computer is running his apache on port 8080 and he is using xp pro, i am using windows 2003 server. The reason my roomate is running on port 8080 is because i am using port 80 and we are making our inside computers accessible to the outside world by using port address translation. I am pretty new to apache and dont know if the problem could be with that or if i missed a step when changing ports. When trying to stream with winamp you get the following error message. "error synching to mpeg." I am wondering if anyone has any ideas as to what may be causing this or have a solution to the problem.

Thanks for help,

Jeff
